Unable to access appsettings.json file in Azure function

Question

I was trying to access my web.config values in Azure Function, but then I came to know that we have to add config values in appsettings.json.

I made those changes and uploaded appsettings.json at azure function location but no luck. my azure function is not reading the values kept in json file.

Please suggest way forward.

What is the your Azure function project target framework? .NET Core or something else? — juvchan

The file local.settings.json stores app settings, connection strings, and settings for Azure Functions Core Tools. It has the following structure:

{
      "IsEncrypted": false,   
      "Values": {
        "AzureWebJobsStorage": "<connection string>", 
        "AzureWebJobsDashboard": "<connection string>" 
      },
      "Host": {
        "LocalHttpPort": 7071, 
        "CORS": "*" 
      },
      "ConnectionStrings": {
        "SQLConnectionString": "Value"
      }
    }

We could get more info about Local settings file from this document.

These settings can also be read in your code as environment variables. In C#, use System.Environment.GetEnvironmentVariable or ConfigurationManager.AppSettings. In JavaScript, use process.env. Settings specified as a system environment variable take precedence over values in the local.settings.json file.

Actually as said by @Mikhail appsettings.json gets ignored.

As Mikhail mentioned that you could use the func CLI to publish settings from your local.settings.json func azure functionapp publish azurefunctionname --publish-local-settings.

You should configure your Function App via Application settings menu item, see example.

appsettings.json or other config files are ignored.

Yes, agree final option is this only. But this is really time consuming process for me as my config has more than 100 keys.

@SharadG You can use func CLI to publish settings from your local.settings.json
